Monitoring

Monitoring involves tracking project progress, site changes, and survey accuracy using Pix4Dmatic.

1. Project Processing Monitoring​

  • Provides real-time feedback during photogrammetry steps:
    • Camera calibration
    • Point cloud densification
    • Mesh, DSM, and orthomosaic generation
  • Built-in quality reports include:
    • Camera alignment success rate
    • Ground Sampling Distance (GSD)
    • Reprojection errors
    • Processing duration and hardware usage
  • Ensures monitoring of accuracy, completeness, and data integrity while projects are running.

2. Spatial Monitoring (Change Detection)​

Used to monitor sites over time by comparing repeated drone surveys:

  • Construction Progress
    • Generate weekly/monthly orthomosaics and DSMs
    • Overlay datasets to track site evolution
  • Mining & Quarry Volume Monitoring
    • Detect material movement or depletion using DSMs and point clouds
    • Compare time-series datasets for volume calculations
  • Infrastructure Monitoring
    • Track roads, powerlines, and city corridors for defects or changes

3. Integration with Pix4Dcloud for Live Monitoring​

  • Upload outputs to Pix4Dcloud for remote monitoring
  • Timeline comparison for project evolution
  • Overlay CAD/GIS data for inspection and reporting
  • Share interactive 3D/2D views with stakeholders

4. Monitoring Accuracy​

  • Use Ground Control Points (GCPs) and checkpoints for survey accuracy
  • Built-in accuracy reports ensure consistency across repeated surveys
